228.06 is what percent of 315 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 315 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 315, so we can write it down as 100%=315.
4. We know, that x% equals 228.06 of the output value, so we can write it down as x%=228.06.
5. Now we have two simple equations:
1) 100%=315
2) x%=228.06
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=315/228.06
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 228.06 is what percent of 315

100%/x%=315/228.06
(100/x)*x=(315/228.06)*x       - we multiply both sides of the equation by x
100=1.3812154696133*x       - we divide both sides of the equation by (1.3812154696133) to get x
100/1.3812154696133=x
72.4=x
x=72.4

now we have:
228.06 is 72.4% of 315
